Macy's says,"Access Denied You don't have permission to access the requested URL on this server. Reference......."

Hi FrustratedMacLady,

The best steps that you can take for any issue with Safari on your Mac can be found here: If Safari doesn't open a page or work as expected on your Mac - Apple Support

These solutions are for issues that can affect Safari on Mac, including issues such as these:

* A webpage is blank, doesn't load all of its content, or otherwise doesn't work as expected.

* You can't sign in to a webpage, despite using the correct sign-in information.

* A webpage asks you to remove or reset cookies.

* Safari slows down, stops responding, or quits unexpectedly.

Should the behavior persist, and just with Macy's page, it is likely an issue on their end. Their support page may open for you as it is separate from their main page: Macy's Customer Service

Regards.

Why is this, and how to correct so that I can shop Macy’s online?

Did you try all the suggestions recommended by Drew_7?

The reason for asking is that Macys.com works just fine on this Mac. It may be a temporary condition.

Yeah, but the problem is that the website is doing this on ALL browsers, not just Mac. So it isn't a Mac/Apple issue.
